Product Description:
Laboratory leach testing procedures include the studies of dissolving metal ions, with a acid, base, cyanide, or other chemicals. The leach column simulates the effects of heap leaching of a ore, in a controlled, lab environment, making data collection quick and easy. In order to eliminate any wall effect in the lab leach columns, the maximum size for each diameter of column should be followed. The 6”diameter by 72” in height column and 10” diameter by 79” in height leach columns are constructed of PVC , and the solution reservoir is constructed of stainless steel. A 10 mesh stainless steel screen may covers the drain plate, to prevent fine grained material from plugging the recirculation pump. The stainless steel drainage plate also serves to support the column of rocks. A peristaltic pump with pvc tubing is used to re-circulate the leach solution. Samples may be easily collected of the leach solution, to monitor temperature, concentration, density, extraction of precious metals, as well as undesirable elements.
The ores placed into the column should be screened prior to inserting, to determine particle size distribution, for later use comparing recovery to particle size. The time required to obtain maximum practical recovery is also an important element to monitor, for use in determining leach rates. Any additives, such as lime to maintain higher pH, should also be noted. And finally, the consumption of the leach solution should be recorded for each test, to determine projected leach consumption rates. Our Laboratory Column Leach System makes conducting lab leach test easy, efficient, and effortless. (Well, practically effortless).
